Beneficial symbiotic bacteria encode an exceptional number of toxin-related genes that are all expressed by the symbionts in the host, supporting their key role in host-microbe interactions.

The genome of Thermovibrio ammonificans encodes ancestral pathways (e.g., hydrogen oxidation) and more recently acquired ones (e.g., nitrate reduction) and a hybrid pathway for CO₂ fixation.

The brain architecture of shrimp living in deep-sea vents provides clues to how these organisms have adapted to extreme living.

A neuroanatomical analysis of Rimicaris exoculata provides insights into these animal’s brain architecture to illustrate possible adaptations to the hydrothermal vent habitat with its extreme physicochemical conditions.

Combining in silico and experimental approaches to identify and understand the residue changes in the H-NS protein that allowed bacteria to adapt environment-sensing to different habitats.

High-throughput, integrative taxonomy has a crucial role to play in ensuring that the resources in our oceans are managed and developed in a sustainable manner.

Physiological differentiation during symbiosis leads to division of labor between smaller and larger cells in an uncultured bacterial tubeworm symbiont population and results in remarkable metabolic diversity and complexity.

The hadal snailfish rapidly evolved and adapted to extreme deep-sea environments, modifying crucial genes and enhancing tolerance to high-hydrostatic pressure through ferritin gene duplication.

Parallel horizontal gene transfer has spread a bacteriolytic gene family to all domains of life, and has bestowed a niche-transcending adaptation in recipients that must deploy antibacterial molecules to survive in a bacterial world.

Single-cell amplified genome sequencing uncovers virus-host interactions in uncultivated sulfur-oxidizing bacteria with relevance to coupled biogeochemical cycling in marine oxygen minimum zones.
